UNITED STATES PATENT OFFICE,

HENRY A. JANACEK, or LA GRANGE, TEXAS.

Application filed July is,

The present invention relates to an apparatus for use upon speeding and racing boats and the prime object of the invention resides in the provision of means to cause the boat to be lifted to safety when said boat strikes a high wave.

v A still further very important object of the invention resides in the provision of an apparatus of this nature which is normally in an inoperative position when the boat is travelling along on comparatively calm water, but automatically fui'ictions as soon as the boat strikes a relatively high wave.

A still further very important object of the invention resides in the provision of an apparatus of this nature which may be easily installed on a boat, is simple in its construction, inexpensive to manufacture, strong and durable, not likely to easily become out of order, thoroughly ellicient and reliable in use and ope ation and otherwise well adapted to thepurpose for which it is designed. p g

Vith the above and numerous other ob jects in view, as will appear as the description proceeds, the invention resides n certain novel features of construction and in the combination and arrangement of parts as will be hereinafter'inore fully described and claimed; I

In the drawings:

Figure '1 is a fragmentary elevation of a boat, showing the bow end thereof with my improved apparatus associated therewith in. the normal position.

Figure 2 is a similar view, showing the apparatus adjusted by relatively high waves.

Figure 3 is a top plan view thereof,

Figure 4 is an enlarged detail sectien, taken substantially on the line 44 of Figure 3,

Figure 5 is a section taken substantially on the line 55 of Figure 3.

' Fig. 6 is adetail view showing the con nection between shaft 22 and the elevator plane.

Referring to the drawings in detail, it will be seen that the numeral 5 denotes a boat particularly a relatively speedy boat such as are used for pleasure and racing purposes. A rocker shaft 6 is journaled across the front end of the boat and has cranks 7, on the outer ends thereof extending rearwardly. On, the ends of the cranks 7 are floats 8. A crank 9 is on the shaft 6, intermediate its ends within the boat, and. is connected 192a. 'seriai- No. 293,080.

with a link 10, which in turn is connected with a crai'lk 11 on a shaft 12, journaled across the boat above the shaft 6 and a little to the rear thereof. A crank 14 from the shaft 12' is connected with a link 15, which is connected with a crank 16, of a shaft 17. A crank 18 is provided on the shaft 17 and has a link 19 connected there with for engaging cranks 21, on the shaft 22 of elevator planes 23, to the sides of the boat having their rear edges fixed to the shaft 22 and extending forwardly normally in a. horizontal position as shown in Fig ure 1, resting on stops 24. Any number of these elevator planes 23 may be provided to each side of the boat and they are operated all in the same manner through additional links 15, and shafts 17. f

From the above detailed description it will be seen that when the boat is going along in relatively calm water as shown in .Figure 1, the float cranks 7 rest on stops 26,

at which time the planes rest on stops 24 Ifthe' boat strikes a relatively high wave as shown in Figure 2, the boatwill be raised,

the float cranks being limited in their upward movement by steps 27, thereby causing the inclination of the elevator planes upwardly and forwardly from their. shafts 22, so as to prevent the boat from cutting through the high waves but causing the boat to rise over the high waves.

It is thought that the construction, operation, utility and advantages of this invention will. now be quite apparent to those skilled in this art, \Vltl'iOllt a more detailed description thereof. The present embodiment of the in-' vention has been disclosed in detail, merely for the purposes of exemplification, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to, without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages,

Having thus described my invention, what Iclaim as new is:

l. In a boat, a pluralityof planes, one or more adjacent to each side of the boat adjacent the bow end thereof, floats to the side of the boat forwardly of the planes, float and planes spaced. above the plane ran...

of displacement, means operatively connecting the floats to the planes so that when the boatstrikes the-relatively high wave and the floats are raised, 'suchplanes will he inclined upwardly with respect to the plane of displacement and forwardly to prevent the boat from diving throu h the wave, but causing it to ride over the waves.

, 2. In a boat, a pair of cranks one on each side of the forward end of the heat, means for rockahly mounting the cranks at the forward ends, floats at the rear ends of the cranks, means limiting the downward move I ment of the floats, a plurality of planes, one

or more to each side of the boat to the rear of the float, means r ckably mounting the rear edges of the plane to the heat, and

means opera-tively connecting the planes with the crank, so that when the floats are raised,

the cranks are inclined upwardly and forwardly. V

3. In a boat, a pair of cranks one on each side of the forward end of the boat, means for rockahly mounting the cranks at the forward ends, floats at the rear ends of the cranks, means limiting the'downward movement of the floats, a plurality of planes, one or more to each side of the boat to the rear of the float, means rockably mounting the rear edges of'the plane to the boat, means operatively connecting the planes with the crank, so thatwhen the floats are raised, the

cranks are inclined upwardly and forwardly, means limiting the downward swlnging movement of the plane.

4. In a boat, a pair of cranks, one on each side of the forward end of the boat, means for roekahly mounting the cranks at the forward ends, floats at the rear ends of the cran as, means limiting the downward movement of the floats, a plurality of planes, one or more to each side of the boat to the rear of the float, means rockahly mounting the rear edges of the plane to the boat, means operatively connecting the planes with the crank, so that when the floats are raised, the

cranks will incline upwardly and forwardly,

means limiting the downward swinging movement-0f the plane, means limiting the upward swinging movement of the'plane.

5. In boat a pair of cranks one on each 7 1 7 1 side of the forwaro end of tne heat, means for rockably mounting the cranks at the forward ends, floats at the rear ends of the cranks, means limiting the downward move HENRY A. JANACEK.
